Unknown Software Exception
« on: January 30, 2019, 06:13:40 PM »
I am unable to install Avast on a laptop. Every time it installs, it always says that it was successful but every time I try to open Avast, I always get

"the exception unknown software exception (0x40000015) occurred in the application at 0xf97ce76f.

Click OK to terminate the program
"

I tried countless repair installs and clean installs but the error message persists no matter what I do

Googling the message only brought up 2014 results. There is absolutely nothing recent or even from 2018, the latest result on this error message is December 2014

Premier/Latest version/Windows 7/AVG (long ago)

I needed to reinstall because the same thing that I mentioned the other day with the "unexpected error" happened on my second PC. Has not happened on the third (yet)

Windows 7 SP1?  If you are not at SP1, Avast does not support original Windows 7 version. 

Example:  Do you have iOBit installed? 

If good, then

-->Uninstall all old versions using link provided!   https://support.avast.com/en-ww/article/11/#artTitle
-->Reboot! after each antivirus removal run.
-->Download aswclear.exe from here:  https://www.avast.com/uninstall-utility
-->Download fresh Offline Installer from here:  https://forum.avast.com/index.php?topic=224223.0
Windows 10 Home 64-bit 1909 Avast Premier Security version 20.10.2442 (build 20.10.5824.618) UI version 1.0.591.
